it's a feature request, not a bug.

What would be the standard to distinguish between a "business email" and a "non-business" one?

[j16h]

@fedeci I would include most popular email domains into the ignore list.

const ignore_public_email_domains = ['gmail.com', 'yahoo.com', 'hotmail.com', 'aol.com', ...]

validator.isBusinessEmail('email@gmail.com') // false
validator.isBusinessEmail('email@github.com') // true

[fedeci]

We may add an option to let the end user to exclude specific domains, but I would not add some default ones.

[j16h]

This sounds like a very good option. However, I'd also include a list of most popular domains, so that users can include the pre-default list of excluded domains.

[j16h]

You know, you are right! The option you mentioned would be more than enough.

[fedeci]

I am working on this.

If it more of business items, I did research and found out that https://hunter.io/email-verifier can offer a better validation.
